|discussion=<p><i>Gemmabryum apiculatum</i> is a nearly pantropical, highly variable species. The plants produce leaf axil bulbils, at least in Paleotropical material; these may represent a microspecies complex. The very long laminal cells, often pinkish tinge to the plants, small brown pyriform tubers, and small distinct group of quadrate alar cells are diagnostic. <i>Gemmabryum valparaisense</i> is similar but has shorter laminal cells, lacks quadrate alar cells, is typically bright green, and has somewhat larger tubers. <i>Gemmabryum</i> sauteri (Bruch & Schimper) J. R. Spence & H. P. Ramsay may be confused with <i>G. apiculatum</i>, but has not yet been reported from North America.</p>
